Cylindrical Roller Bearings FAG NJ311 -E-XL-TVP2-C3

The single-row cylindrical roller bearing NJ311 -E-XL-TVP2-C3 from FAG (55x120x29 mm) can accommodate high radial loads as well as unilateral axial forces.

With the NJ311 -E-XL-TVP2-C3 cylindrical roller bearing, FAG offers a roller bearing for demanding industrial applications. The design features a bore of 55 mm, an outer diameter of 120 mm and a width of 29 mm. As an open, single-row bearing without an integrated seal, it is designed for external lubrication systems. The polyamide cage guides the low-mass cylindrical rollers, which promotes smooth running.

What is the NJ311 -E-XL-TVP2-C3 cylindrical roller bearing suitable for as a support bearing?

The NJ design is specifically engineered as a support bearing. Two fixed flanges on the outer ring and one fixed flange on the inner ring enable shafts to be guided in an axial direction. At the same time, the design allows for axial displacement in the opposite direction, thereby compensating for changes in length due to heating. This design is primarily intended for bearing arrangements in which, in addition to very high radial forces, defined guiding forces act in one direction.

What advantages do the polyamide cage and C3 clearance offer with this bearing?

The designation TVP2 refers to a polyamide window cage, which responds elastically to vibrations and reduces the bearing weight. Together with the increased radial clearance (C3), this component is suitable for applications involving operational heating or press fits on the shaft and housing. The increased radial clearance helps to prevent thermal stress during operation. The permissible temperature range is from -30 to +120 degrees Celsius.
